1. Why Horizontal Axis Wind Turbines have 3 Blades? (most popular wind power faqs)
What happens when wind turbines have more or fewer blades? By and large, most wind turbines operate with three blades as standard. The decision to design turbines with three blades was actually something of a compromise. Because of the decreased drag, one blade would be the optimum number when it comes to energy yield. However, one blade could cause the turbine to become unbalanced, and this is not a practical choice for the stability of the turbine.
Similarly, two blades would offer greater energy yield than three but would come with their own issues. Two-bladed wind turbines are more prone to a phenomenon known as gyroscopic precession, resulting in wobbling. Naturally, this wobbling would create further stability issues for the turbine as a whole. This would also place stress on the component parts of the turbine, causing it to wear down over time and become steadily less effective.
Any number of blades greater than three would create greater wind resistance, slowing the generation of electricity and thus becoming less efficient than a three-blade turbine. For these reasons, turbines designed with three blades are the ideal compromise between high energy yield and greater stability and durability of the turbine itself.

2. Why Wind Turbines are White?
Why are wind turbines white? Believe it or not, it is more aesthetically pleasing than otherwise. Painting them white or light grey helps the entire structure “blend” into the background, especially when the sky is cloudy.
City planners, in general, seem to hold the consensus that the color white is less of an eye-sore than others. By making the entire structure white, the wind turbine is less visually obtrusive, in theory at least. White, after all, is a pretty neutral color.
Apart from the contradiction of the white coloration helping them stand out whilst almost making them blend in, it also helps protect them from the elements. The white coloration helps reflect UV radiation during the daytime.
UV famously degrades many materials over time. Given the exposed nature of wind turbines, not to mention the significant cost for installation, any strategy that can be employed to extend their lifespan is, of course, highly beneficial.
Generally speaking, colors, especially darker shades, tend to absorb sunlight and more importantly heat. White, on the other hand, tend to reflect sunlight and therefore heat. Heat causes things to expand, dry up lubrication, and could cause blistering given enough time.

3. Why Wind Turbines are Bad for the Environment?
The environmental impact of wind power is relatively minor when compared to that of fossil fuel power. Compared with other low-carbon power sources, wind turbines have one of the lowest global warming potentials per unit of electrical energy generated by any power source.
Onshore wind farms can have significant impacts on the landscape,[5] as typically they need to be spread over more land than other power stations and need to be built in wild and rural areas, which can lead to “industrialization of the countryside” and habitat loss. Habitat loss and fragmentation are the greatest impacts of wind farms on wildlife. Wind turbines, like many other human activities and buildings, also increase the death rate of avian creatures such as birds and bats.
As with all energy supply options, wind energy can have adverse environmental impacts, including the potential to reduce, fragment, or degrade habitats for wildlife, fish, and plants. Furthermore, spinning turbine blades can pose a threat to flying wildlife like birds and bats.
Due to the potential impact, that wind power can have on wildlife, and the potential for these issues to delay or hinder wind development in high-quality wind resource areas, addressing impact minimization, siting, and permitting issues are among the wind industry’s highest priorities. Most wind power projects on land require service roads that add to the physical effects on the environment. Producing the metals and other materials used to make wind turbine components has impacts on the environment, and fossil fuels may have been used to produce the materials. (Wind power faqs 3)

4. Why Wind Turbines are Good for the Environment?
Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling.
Wind turbines may also reduce the amount of electricity generation from fossil fuels, which results in lower total air pollution and carbon dioxide emissions. Most wind power projects on land require service roads that add to the physical effects on the environment. Producing the metals and other materials used to make wind turbine components has impacts on the environment, and fossil fuels may have been used to produce the materials. (Wind power faqs 4)

5. How do Wind Turbines Affect the Atmosphere?
Modern wind turbines can be very large machines, and they may visually affect the landscape. A small number of wind turbines have also caught fire, and some have leaked lubricating fluids, but these occurrences are rare. Some people do not like the sound that wind turbine blades make as they turn in the wind.
Some types of wind turbines and wind projects cause bird and bat deaths. These deaths may contribute to declines in the population of species also affected by other human-related impacts. The wind energy industry and the U.S. government are researching ways to reduce the effect of wind turbines on birds and bats.
